简介地表下沉可以引起地面构筑物的严重损坏。在矿区,构筑物下方由于需要留设保安矿柱而减少了矿井的服务年限和降低全部矿物资源的回收率。为了预计地表下沉,需要变形力学和地层物理性质的知识。急倾斜矿层上方地表下沉的研究较少,因而所了解的变形之间的相互影响当然就比缓倾斜矿层的更少。本论文研究的是急倾斜矿体开采时的地表下沉。除了上山方向可能出现地表隆起外,而地表下沉的现象相似于开采水平
Introduction Surface subsidence can cause serious damage to ground structures. Under the mining areas and structures, the service life of the mine and the recovery rate of all mineral resources are reduced due to the need to set up security pillars. In anticipation of surface subsidence, knowledge of deformation mechanics and the physical properties of the formation is required. There is less research on the surface subsidence above steeply pitched mines, so the interactions between the deformations understood are, of course, less than those of the gently inclined mines. This thesis is about the surface subsidence during the mining of steeply inclined orebody. In addition to the uphill direction may surface uplift, while the phenomenon of surface subsidence similar to the level of exploitation
